Engine wont start - cranks OK - NOW WITH VIDEO

[Apolan]

Spend up until now trying to get my engine to fire for the first time since rebuild - no luck!

The situation as follows:

- injectors spray fuel (i used the 210cc ones from afm engine)
- spark plugs give spark (in correct order)
- hopefully i have sufficient compression - its a fresh rebuild

Engine cranks ok. Now that i changed the ground of the battery even better, not sure its optimal tho. For a second it sounded/smelled like it fired a cycle or two, but no luck in getting it to run.

Im not sure about the timing, need to set that. Tried adjusting the distributor slightly, but no luck.

Any ideas? Could it be that the ground is still to weak (now its on engine head). Could it be that the timing is so far off?

Thanks for your time!
